The timeline's all wrong. Being born a year before DMC3 would make Nero something like 14 at the absolute maximum. Half of the problem with Nero being Vergil's son at all is the age problem and this only exacerbates it. Not to mention the fact that there's nothing in DMC3 or the Manga to suggest that they knew each other... Heck, watch any cutscenes where Vergil is talking to Lady or about Lady and you'll have to really, really project your intentions to get the impression that he knew her let alone fathered her child.
